I'm looking at upgrading to a 11.5K loaded fifth wheel.
I currently tow a 6K TT.
Truck is Bone stock except for (DP infinity tuner and a 6.0L Trans Cooler)
2000 F250 7.3L CCSB SRW auto 4x4 Lariat 3.73 with 90K miles.
I live in the Pacific NW so passes and grades are part of life here.
So question goes to you guys with turbo 7.3L towing around 11-12k
whats your speed, RPM, gear when ascending and most important what
have you done, or has been done to your truck to accommodate the pull.
Thanks in advance.
I spent nearly 16 years towing with a 7.3. F350. I towed from 7k-13K. The truck did pretty good in the mountains until I went to my present fifth wheel at 13K, then it pretty much fell on its face. It was okay on the flat, pretty slow getting going on freeway on ramps , and struggled in the mountains . It did just okay under 10k, but as said not good over 10K.
I did about all you could do to make it run better without doing injectors ,and turbo. DP tuner, 4" exhaust , 6.0 transmission cooler, and intercooler, plus AIS air intake. Of course gauges for EGT's, transmission, and turbo.
First off you don't have the power with that 7.3, and you are overloaded with that F250 if trying to tow a 12K fifth wheel. You will not be happy unless you are towing in Kansas :) Then it still won't be pleasant.
